Low density Polyethylene resin
Low-density polyethylene (LDPE) is a synthetic resin inoshandisa high pressure process kuburikidza nemahara radical polymerization ye ethylene uye nekudaro inonziwo "high-pressure polyethylene".Sezvo cheni yayo yemamorekuru ine matavi mazhinji marefu uye mapfupi, LDPE haina crystalline pane yakakwirira-density polyethylene (HDPE) uye density yayo yakaderera.Inoratidzira chiedza, inoshanduka, yakanaka yekudzivirira kutonhora uye kukanganisa kwekudzivirira.LDPE yakagadzikana mumakemikari.Iine kumira kwakanaka kune acids (kunze kweiyo yakasimba oxidizing acids), alkali, munyu, yakanakisa magetsi ekudzivirira zvinhu.Kupinda kwayo kwemhute kwakaderera.LDPE ine yakakwira fluidity uye yakanaka processability.Yakakodzera kushandiswa mumhando dzese dze thermoplastic processing process, senge jekiseni rekugadzira, extrusion molding, blow molding, rotomolding, coating, foaming, thermoforming, hot-jet welding uye thermal welding.
Application
LDPE inonyanya kushandiswa kugadzira mafirimu.Inoshandiswa zvakanyanya mukugadzira firimu rekurima (mulching firimu uye yakadururwa firimu), yekurongedza firimu (yekushandisa mukutakura zvihwitsi, miriwo uye chikafu chakaomeswa), firimu rinopeperetswa rekurongedza mvura (yekushandisa mukurongedza mukaka, soy muto, muto, bhinzi nemukaka wesoya), mabhegi ekurongedza anorema, shrinkage yekurongedza firimu, elastic firimu, lining firimu, firimu rekuvaka, general-chinangwa maindasitiri ekurongedza firimu uye mabhegi ezvekudya.
LDPE inoshandiswawo zvakanyanya mukugadzira waya & tambo yekumisa sheath.Muchinjikwa-yakabatana LDPE ndicho chinhu chikuru chinoshandiswa mune yekuvharisa layer yeakakwira-voltage tambo.
LDPE inoshandiswawo mukugadzira zvigadzirwa zvakaumbwa nejekiseni (zvakadai semaruva ekugadzira, zviridzwa zvekurapa, mushonga uye zvinhu zvekurongedza zvekudya) uye machubhu akaumbwa, mahwendefa, waya & tambo dzekupotera uye zvigadzirwa zvepurasitiki zvakadhindwa.
LDPE inoshandiswawo kugadzira zvigadzirwa zvakaputirwa nemhepo zvakaita semidziyo yekubata chikafu, mushonga, zvekuzora uye zvigadzirwa zvemakemikari, uye matangi.
Package, Kuchengeta uye Kutakura
Iyo resin inoputirwa mukati memukati firimu-yakavharwa polypropylene yakarukwa masaga.Huremu hwemambure i25Kg / bhegi.Iyo resin inofanira kuchengetwa munzvimbo yakaoma, yakaoma uye kure nemoto uye zuva rakananga.Hazvifanirwe kuunganidzwa pamhepo.Panguva yekufambisa, chigadzirwa hachifanirwe kuratidzwa kune chiedza chezuva chakasimba kana mvura uye hachifanirwe kutakurwa pamwe chete nejecha, ivhu, zvimedu zvesimbi, marasha kana girazi.Kufambisa pamwe chete nezvinhu zvine chepfu, zvinopisa uye zvinopisa zvinorambidzwa zvachose.
